' NITED I STATES PATENT FFICEG CHARLES L. BATES, OF NEW YORK, N.

GONG-BELL.

SPECIFICATION formingpart of Letters Patent No. 231,752, dated August 31, 1880.

Application filed J une 5, 1880. (Modch) To all whomet may concern:

Be it known that I, CHARLES L. BATES, of the city, county, and State of New York, have invented a new and useful lmprovement in Gong-Bells, of which the following is a specification.

Figure l is a plan view of theimprovement, the bell being removed. Fig. 2 is a side elevation of the same, the bell being shown in section.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish gong-bells so constructed as to give a heavier blow with a shorter stroke than those constructed in the ordinary manner, which can be adjusted for use as a right-hand or a left-hand bell, as required, and which shall be simple in construction and not liable to get out of order.

The invention consists in constructing a gong-bell of a frame having a stud and bell, the hammer-lever and its stop, the angle triplever having a toe, an incline, and a shoulder and its stops, the spiral spring, the wire lever having notch, and the two studs having screw holes, whereby the hammer-lever is operated by the movement of the trip-lever and the action of a single spring, as will be hereinafter fully described.

A represents the plate or frame of the bell. To the middle part of the frame A is attached the post B, that carries the bell O.

D is the hammer-lever, which is curved to bring its free end into such a position that the hammer-head will strike the bell fairly. The hammer-lever D is pivoted near its rear end to the frame A by a screw, E, and its forward movement is stopped at the proper point by a stop, F, attached to the frame A.

G is the trip-lever, which has a projection or toe, H, upon the end of its long arm g, which engages with the end of the hammerlever D to draw back the hammer to give a blow. Just above the toe H are formed two bends at nearly a right angle, and near the pivot-screw I two bends at an obtuse angle.

The trip-lever G is pivoted at its angle at the other side of the frame A from the ham-' mer-lever D, by a screw, I, to the lever J, which is pivoted at one end to a corner of the frame A by a stud, B, and screw K, and to its other end is attached the bell-wire L. To the end of the short arm 9 of the trip-lever G is attached the end of a spiral spring, M, the other end of which is attached to the hammerlever D.

With this construction, when the bell-wire is pulled the lever J is moved outward, which draws back the trip-lever G, causing the toe H to draw back the hammer to give a blow, and at the same time increasing the tension of the spring M.

Upon the long arm of the trip-lever G is formed an incline,N, which rests againstastoppin, 0, attached to the frame A. As the triplever Gr is drawn back by the movement of the wire lever J, the stop 0, acting upon the incline N, pushes the said trip-lever G outward and withdraws the toe H from the end of the hammer-lever D, and allows the hammer to be drawn forward by the tension of the spring'M to strike the bell O.

The outward and rearward movement of the trip-lever G is limited by a stop-pin, P, attached to the frame A, and against which a shoulder, Q, formed upon the said trip-lever G, strikes.

The screw K screws into a screw-hole in the stud It, attached to the corner of the frame A, which stud serves as a pivot to the lever J. In the inner edge of the lever J, toward the end to which the wire L is attached, and at an equal distance with the hole for the studRfrom the hole for the screw I, is formed a notch, S, to receive the stud T, attached to the corner of the frame A, and which serves as a stop to prevent the said lever J, when the tension upon the wire L is relaxed, from being drawn too far inward by the spring M. The stud T has a screw-hole formed in it to receive the screw K.

With this construction, by taking out the screws I and K, reversing the lever J, replacing the screw I, and inserting the screw K in the stud T, the bell is changed from a righthand to a left-hand bell.

This construction makes the bell very convenient in use, as the bell-hanger can adjust the bell in a minute for attachment to the wall at either side of the doorway, as may be required.

I am aware that it is not new to use a sliding lever to which the wire is attached, provided with a V-shaped projection and a notched end to engage a lug on its hammer, the said lever being connected with the hammer by a spring.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 1. A gong-bell constructed substantially as herein shown and described, consisting of the frame A, having stud B and bell O, the angle trip-lever G, having toe H, incline N, and

shoulder Q, the spring M, the wire lever J, the

studs R T, having screw-holes, and the stops F O P, as set forth.

2. In a gong-bell, the combination of the 15 wire lever J having the notch S at the same distance from the trip-lever G as the pivot-hole in the end of said lever, with the internallythreaded studs R T, as and for the purpose specified.

CHARLES L. BATES.
